Greetings!
i have another PC.
i bought a 22-inch Chimei LCD, for that PC, back in February. i have seldom used that PC since then.
i have encountered a problem with it, which has never happened before ---- the PC automatically shuts down. it happened again today (it's the 2nd or 3rd time it happened).
pressing the power button does not/cannot turn the PC on (PC does not boot). but i noticed the keyboard & mouse are still lit on (remember the PC is off). i can turn the monitor on too, but of course, there is no image/monitor is black.
the last time it happened... what i did was let the PC rest for a few minutes, reconnect the power cords to the AVR (auto. voltage regulator), then it turns on & works ok, like nothing happened.
if it helps, that PC has been having a ringing sound during boot time, since mid2009-Jan2010.
i do not have an idea what the cause is.
but my guess is that the problem has something to do with the new monitor.
the old monitor was a 15" samsung LCD.
..another guess is the power supply. since i upgraded to a bigger monitor, this may be related to it. (a few minutes ago, right after the PC auto shut down, i touched the Power supply casing it was relatively hot)
my power supply is 300W, it came with the PC when i bought/assembled it around 6yrs ago..
Hopefully someone can help
Thanks all!
